Finance System exposes an API platform for integration clients, with self-service administration for API credentials and scoped access rather than blanket database access. This is the same integration surface used for business banking read/write operations (accounts, transactions, transfers) under proper authentication.

• Integration Client administration for issuing and revoking API access
• Scoped, authenticated API endpoints for accounts, transactions, and transfers
• A connector framework for synchronizing with an External ABS during migration

No private Backoffice endpoint or internal-only route is ever exposed through this public API surface.
